IMHO the most effective speedup for most users is to write custom guest device drivers for IDE/network/video that talk directly to qemu using some low overhead mechanism. Basically you want the guest to do as little as possible. The problem is that to be really useful you need to write open source drivers for the common operating systems (win9x, winnt/2k/xp, Linux, *BSD) Paul
